pm_ptr() is for drivers implementing Runtime PM or a mix of
runtime and sleep PM.

The proper macro seems to be to use pm_sleep_ptr() for drivers
only implementing system sleep callbacks (suspend/resume).

See e.g.
408ba1d06ee1 ("spi: bcm63xx-hsspi: use modern PM macros")
65172b5d381a ("spi: dw-pci: use modern PM macros")


Kind regards,
